Harmony appeared serious BUG(Maybe...)

Well, today (February 19, 2020), when I try to play RimWorld found the red error, and cannot regenerate into a map. I confirm after shut down other mod is AlienRaces appeared problem, but because of my lack of knowledge, in truth, I don't know what's going on, so I can only attach the error log.(And...I'm sorry, I am a grade seven students from China, the English may seem strange, because I'm not good at English, I use youdao translation.) ——Error log.——

Could not execute post-long-event action.
